I'm new to this forum. We traded our Jayco hybrid for a '16 Freedom Express 257BHS. Two issues, I sanitized the water system today and noticed a small puddle at the water pump. I expect I just need to tighten a fitting but is this a normal problem with Coachmen build? Also, I went searching for a fresh water winterizing siphon but didn't see it at the water pump. However the water pump is pretty much inaccessible as it is located in a corner under the corner mount kitchen sink. I have long arms and can hardly reach back there after pulling out 2 drawers. A winterizing siphon is not mentioned in the Forest River manual. The manual suggests dumping 5 gal of RV antifreeze in the water tank. Has anyone been able to install the siphon at the pump.

There are also hand pumps that pump anti-freeze at the city water connection. Would that be a viable alternative to winterize the water pump?
I know cold weather is 6 months away, but I want to become informed about the differences with winterizing this trailer.

Last question, my dealer never installed the toilet paper holder. There were no screws in the package. How long of a screw do you guys suggest?

Thanks for your help
Looking forward to years of fun in the new trailer
